McGill scored 25 with four 3-pointers and had six assists while Casimir scored 22, also with four treys and the third-seeded Gaels (20-12) advance to meet No. 2 seed St. Peter's (19-6) in a Sunday semifinal. Iona defeated St. Peter's 69-66 in overtime at the end of January.

Rider, the No. 6 seed, lost in the MAAC quarterfinals for the sixth-straight season.

The Broncs came as close as 53-46 on a Stevie Jordan layup with 17:15 to play but shortly afterward Rider was held scoreless for more than five minutes while the Gaels went on a 9-0 run.

Jordan led Rider with 19 points, Kahlil Thomas and Xavier Lundy scored 13 each while Norville Carey added 12. Thomas added 10 rebounds for his twelfth double-double and Jordan also doubled up with 12 boards.
